Arch Download

Note that the RPi web site Arch direct download is not necessarily the same as the Arch included in the NOOBS package!  In our tests we found they we're different versions with distinct differences as soon as we tried to install things.  The NOOBS version seemed the better in terms of things working but it was still very problematic.

After installing update all packages

pacman -Sy
pacman -Syu
